"It is very important for everyone to have smiled at a stranger, to have helped somebody they will never see again, to have done something kind and/ or nice for somebody with no strings attached, and to have loved somebody unconditionally. There will always come a time, sooner or later, when each of us will feel that we have nothing left to give to this world, or that this world has everything and does not need anything more from us. At that time, only if we have done the above, will we be able to believe that this world is still capable of smiling at us, helping us, being kind and nice to us, and above all, is capable of loving us."
